\Li*thog"ra*phy\, n. [Cf. F. lithographie.]
The art or process of putting designs or writing, with a
greasy material, on stone, and of producing printed
impressions therefrom. The process depends, in the main, upon
the antipathy between grease and water, which prevents a
printing ink containing oil from adhering to wetted parts of
the stone not covered by the design. See {Lithographic
limestone}, under {Lithographic}.
